I’ve replied to your question here: TI-84 Plus CE - ON Button Not Working To Turn On or Off
That’s interesting, does your computer recognize it when you plug the calculator in?
Just so you know, the charging circuit is separate from the rest of the calculator so it can still work even if the calculator doesn’t.
So you're saying when you try charge the calculator it doesn't charge the battery at all? Does the LED next to the charging port turn solid orange when you plug it in? Have you tried a different power source (i.e. your computer or a wall block) or a different cable?
@tfc_cnc Hi, first off I really appreciate all the information you provided, it makes this a lot easier to diagnose! Unfortunately if reinstalling the OS (step 4) does not work, then there’s nothing more you can try on the software side. However, If the battery indicator never turns green even after charging overnight then there may be a defect with the battery itself. Try replacing the battery; if that doesn’t work then I think you’ll need to contact TI Cares. I have no idea why some calculator just die for no reason. Please let me know if you get it working again!
You can’t buy replacement parts for either one without finding a donor calculator somewhere. If it’s just the screen protector that’s damaged then you can just pull it off since it’s only held on by weak glue. If your LCD is cracked then you’ll need to find another TI 84 Plus CE and swap the LCDs. Fortunately all displays are compatible with all hardware revisions so it doesn’t matter which one you get (just make sure you do NOT get a TI 84 Plus CSE since it does NOT have the same LCD).
@Infine Axel, I think this is the exact question topic you’re looking for: Why my charging light is always on? It kills the battery..
Oh no! What do you mean by “ when I pulled the screws, the screws came off the cover, like they are completely jammed”? Are you saying the screws on the battery compartment fell out? If so, that’s not normal. They should stay on the battery compartment.
Do you have any idea why your calculator could have suddenly died like this? How long have you had it? It’s possible it could just be defective.
I know you said it wouldn’t turn on, but perhaps you could try connecting your calculator to power then trying TI-84 Plus CE Recovery Techniques. ?
@forestguzman That’s not really an easy project. Perhaps there’s something wrong elsewhere in the calculator that’s easier to fix. Can you please tell me exactly what’s wrong with your calculator? Have you tried looking at TI-84 Plus CE Recovery Techniques. ?
For a project like that I’d suggest making a topic on a calculator forum like Cemetech.net or tiplanet.org since there are many people with more knowledge on that than I have.
Sadly, even if you got a different color, a body swap isn't easy. There's heat melted and glued parts that are difficult if not impossible to put back. Your best bet is to try and glue it back together, or try and use the warranty to get a new calculator. :/
@evankaba Well the goal is to buy a cheap, broken calculator not a brand new one. Unfortunately it’s quite difficult to find a broken TI 84 Plus CE. It’s also very difficult to find replacement parts since TI sources many parts directly from manufacturers. Could you share what’s wrong with your calculator and which part you need? I might be able to help you out.
